Transient ablation of Teflon in intense radiative and convective environments

摘要: On the basis of this investigation high-temperature behavior polytetrafluoroethylene (PTFE), transient one-dimensional ablation PTFE has been developed by taking into account optical transmittance both amorphous zone and crystalline layer. Results show that although exposed surface receded at an apparently steady state, internal temperature thickness gel layer increase continuously due to absorption radiation.
